  15. Summary of Systems Features and Operation DYNAMIC DESIGN PHARMA, INC. - Mission Viejo, California USA

  16. Systems Features - GIT-P4 and GIT-XA1  Programmable parameters  Clear Pass/Fail test result feedback to the operator  Numeric test result feedback (pressure value at the end of test)  Print out of Test Results data  Positive or Negative pressure test (capability)  Self Test capability for cycle development and on-going maintenance  In-Situ Calibration capability  Capable of testing just the glove or the glove/sleeve assembly  Cost effective  Simple operation, validation, training and maintenance DYNAMIC DESIGN PHARMA, INC. - Mission Viejo, California USA

  17. Operation Sequence - GIT-P4 STEP 1: The operator installs the glove interface to the glove to be tested STEP 2: The operator assures that the appropriate channel is enabled STEP 3: The operator starts the leak test cycle Step 4: At the end of the leak test cycle, the operator reviews the results and initiates printing Step 5: The system prints out the test results and the cycle concludes NOTE: GIT-XA1 operation is identical except for the channel selection function DYNAMIC DESIGN PHARMA, INC. - Mission Viejo, California USA

  18. Principle of Operation DYNAMIC DESIGN PHARMA, INC. - Mission Viejo, California USA

  19. Principle of Operation – GIT-P4 and GIT-XA1 systems The system detects a leak in the glove under test by comparing the internal pressure of the glove to a pass/fail pressure threshold level after having been pressurized to a set level and held in a sealed condition for a given time duration. This methodology of leak detection is called pressure decay. DYNAMIC DESIGN PHARMA, INC. - Mission Viejo, California USA

  20. Phases of the Leak Test Cycle GIT-P4 and GIT-XA1 Systems INFLATE Initial pressurization to set point value STABILIZE Maintain pressure at a set level for a programmed time duration to allow glove material to stretch DEFLATE Allow pressure to drop to the leak test starting pressure level LEAK TEST Close off the opening to glove under test for the programmed time duration and monitor the internal pressure level. LEAK TEST END At the end of the Leak Test phase, the pressure internal to the glove under test is compared to the programmed Pass/Fail pressure level. The system then makes the leak test outcome decision and displays the result on the OIT DYNAMIC DESIGN PHARMA, INC. - Mission Viejo, California USA

  23. Positive vs. Negative Pressure Testing Positive Pressure Leak Test - Non-Sterile/Containment Testing Glove/Sleeve is pressurized from outside the isolator In the event of a leak being present in the test item, positive pressure inside test item causes air flow into the isolator system. Negative Pressure Leak Test - Sterile Testing Glove/Sleeve placed under vacuum from outside the isolator In the event of a leak being present in the test item, negative pressure outside the test item causes air flow out of the isolator system. NOTE: Both Dynamic Design Pharma glove tester models are available in positive or negative pressure test mode DYNAMIC DESIGN PHARMA, INC. - Mission Viejo, California USA

  24. In-Situ Calibration Concept In-situ calibration applies to the system as a whole. After calibration, the pressure transducer instrument’s output is modified by calibration factors that are automatically calculated during the calibration procedure. Calibration Process The calibration process consists of a step by step sequence that is menu driven by the control system via the system’s OIT. The pressure values measured during the sequence are automatically used in an algorithm that calculates compensating factors for the pressure output of the system’s pressure transducer.

System Capability Negative pressure, glove only Hole size detection capability = 100 um (0.004 inches) or larger Parameters to achieve above capability (guideline only) • Pressure Threshold = 1500 pa • Inflate time: less than 10 seconds • Stabilization = 60 seconds • Leak test = 120 seconds (< 30 sec. with pressure trending) Aseptic application => glove tested under negative pressure DYNAMIC DESIGN PHARMA, INC. - Mission Viejo, California USA

  26. System Capability Positive pressure, gauntlet Hole size detection capability = 250 um (0.010 inches) or larger Parameters to achieve above capability (guideline only) • Pass/Fail Pressure = 600 pa • Inflate time: 60 seconds (approx.) • Stabilization = 120 seconds • Leak test = 240 seconds Containment application => gauntlet tested under positive pressure DYNAMIC DESIGN PHARMA, INC. - Mission Viejo, California USA
